### Titration Problems and Calculations **15.82** Consider the titration of 50.0 mL of a 0.100 M solution of the protonated form of the amino acid alanine (\( \text{H}_2\text{A}^+ \); \( K_{a_1} = 4.6 \times 10^{-3} \), \( K_{a_2} = 2.0 \times 10^{-10} \)) with 0.100 M NaOH. Calculate the pH after the addition of each of the following volumes of base: (a) 10.0 mL (b) 25.0 mL (c) 50.0 mL (d) 75.0 mL (e) 100.0 mL **15.83** Consider the titration of 25.0 mL of 0.0200 M \(\text{H}_2\text{CO}_3\) with 0.0250 M KOH. Calculate the pH after the addition of each of the following volumes of base: (a) 10.0 mL (b) 20.0 mL (c) 30.0 mL (d) 40.0 mL (e) 50.0 mL **15.84** The equivalence point was reached in titrations of three unknown acids at pH 9.16 (acid A), 8.88 (acid B), and 8.19 (acid C). (a) Which is the strongest acid? (b) Which is the weakest acid?
